omrsn DAVID LONDON, OF BALTIMORE, MARYLAND.

Application filed October 4, 1924. Serial No. 741,611.

To allw/wmit may concern:

Be it known that 1. DAVID LONDON, a citizen of the United States, and aresident of Baltimore, ll'faryland, have invented cer tain new anduseful Unsecured separable Fasteners for Mattress Covers and the like,of which the following is a specification.

This invention relates to snap fasteners particularly suitable andintended for articles that are to be washed and the main object of theinvention is the provision of a snap fastener that is capable ofassociation with such an article in operative fashio without beingsecured thereto.

Heretofore snap fasteners have not been used in unsecured relation withthe particular article. but, on the other hand, have been securedthereto in permanent fashion with the result that such fasteners areusually distorted and made useless during the laundry process. Also, thearticle bearing the fasteners are very frequently ripped and torn, orotherwise mutilated, in the process of laundering by reason of thepermanent association of the fasteners with the article. The inventionherein set forth obviates all these disadvantages.

The snap fasteners comprising my inven tion are especially suitable forthe closure flap of mattress covers that are placed over the type ofmattress commonly used. Such mattress covers require a comparativelylarge number of fasteners and to secure them requires much time andeffort, it being impossible to remove them without mutilating both thefasteners and the mattress cover, whereas mv fasteners being totallyunsecured may be placed in operative association with the cover andremoved therefrom in a very short time and without any trouble orappreciable effort. Other advantageous uses for the fasteners will berecognized in view of this disclosure.

For a complete understanding of the invention reference is to be had tothe following description and the accompanying drawing in which:

Fig. 1 is a fragmentary perspective view of a mattress cover having aclosure flap provided with unsecured fasteners of the type embodying myinvention;

Fig. 2 is an enlarged detail view of the flap showing the eyelet throughwhich the head of the fastener passes;

F 3 is an enlarged sectional view on the line 3-3 of Fig. 1; and

Fig. 4 is an enlarged top plan view of the socket member.

Referring to the drawings in detail, the reference character 10designates the mattress cover having the closure flap 11 provided witheyelets 12 which match the eye lets 13 in the bottom and side portionsof the cover. These eyelets 12 or 13 are made in any suitable manner andmay be made as ordinary button holes are made being reinforced bystitching 14, for example, as shown by Fig. 2. One part of the separablefastener passes through the aligned openings 12 and 13 and the otherpart is separablv attached thereto to thereby hold the fastener inplace.

Referring to Fig. 3, the reference character 15 refers to the head partof the fastener and the socket part is designated by the referencecha'acter 16. The head part is preferably made from a single piece ofmetal and comprises a stud 17 having the peripheral groove 18 and thebottom annular flange 18. The socket is of the resilient type andcomprises the external button 19 and the internal cap 20 having a flange21 having spaced radial divisions 21 to impart resiliency thereto. Froman inspection of 3 it will be noted that the eyelets 12 and 13 are butslightly larger in diameter than the stud 17 and the stud 17 is of suchlength as to receive the two layers of the closure between the flange 18of the head part of the fastener and the socket without permittingexcess longitudinal movement of the stud through the eyelets. While 1have shown the part 11 as a closure flap for mattress covers, it will beunderstood that this part may be merely the marginal portion of anyarticle and 11 which designates on the drawing the bottom marginalportion of a mattress cover may designate the marginal portion of anyarticle, these marginal portions 11 and 11 overlying, by preference,with the eyelets 12 and 13 in alignment for the passage therethrough ofthe studs 17 which are held in place by the sockets 16.

While I have shown and described the preferred embodiment of theinvention, it is to be understood that certain changes in theconstruction and arrangement of parts may be made without departing fromthe inven tion and the invention is not to be considered as limited tothe specific disclosure except Within the terms of the appended claim.

\Vhat I claim is:

A separable fastener for securing apertured marginal portions togethercomprise ing a head member having a flange at one end thereof and anannular groove intermediate its ends, and a socket member com prising arigid outer member having a continuous surface on one side thereof andan opening in the other side thereof, and a resignature.
